Ultra-wide-input DC-DC converters target industrial, railway apps

Flex Power Modules introduces the PKE-A series of dc-dc power modules for the Industrial and Railways sectors, broadening its product range to meet increasing demand in these sectors. The modules are provided in sealed and encapsulated packaging, to ensure they will work reliably when subjected to dust, moisture, severe vibration and other harsh conditions.

For Industrial applications, the PKE8000A series provides highly reliable, high-performance and rugged dc-dc solutions in the industry-standard 2 x 1in form factor, running from 12V, 24V or 48V supply voltages thanks to its ultra-wide-input range of 9 to 75V. Delivering up to 40W of output power at up to 91% efficiency, the series also offers mean time between failures (MTBF) of up to 4 million hours, and input-to-output isolation of 2250VDC. The devices meet the latest IEC/EN/UL62368-1 safety standards.

For Railways applications, the PKE7000A series is packaged in the same 2 x 1in industry-standard form factor, but this time operates from a 43 to 160V input, delivering up to 30W. This makes it suitable for the majority of onboard requirements running from 72V and/or 110V nominal supplies, most commonly found in the Railways sector. The devices comply with the EN50155 railway standard and offer MTBF figures of up to 5 million hours to satisfy the most demanding applications.

Both the PKE8000A and PKE7000A families are available now for sampling and volume production requirements.
